Hybrid Cashew Seedlings (Jumbo Varieties)

Description

CASHEW VERSIONS

Brazilian cashews, Chinese cashews, and Indian cashews are the three main types. Nigeria is where Nigerian cashew is primarily farmed.

Since cashew is heavily cross-pollinated, commercial-scale vegetative propagation is primarily advised to create planting materials that are true to type.
Three to four nuts can be sown in each hole, or the nuts can be grown in a nursery and then planted in the field.
One healthy and robust plant is left in each stand after the plants have been trimmed off the following establishment.
Cashews can be multiplied using softwood grafts, air layers, and seedlings.

SPREADING VIA SEEDLINGS
choosing mother trees
The chosen mother trees should have strong growth, extensive branching, and a high proportion of hermaphrodite blooms in their panicles. They should also be in good condition.

With an average yield of 15 kg of nuts per year and 7-8 nuts per panicle, the trees should produce nuts that are medium in size and weight (5-8 g/nut).

raising young plants
In May, grow seedlings in plastic bags. To speed up germination, soak seed nuts in water for 18 to 24 hours. Plant the pre-soaked seed nuts with the stalk end up, 2-3 cm deep, in polythene bags filled with garden soil. In seven to ten days, seeds begin to sprout.

a variety of seed nuts
During the peak of the harvest in February and March, fresh seed nuts should be harvested and sun-dried for two to three days.

To produce seedlings that are uniform and grow quickly, medium-sized nuts between 7 and 9 grams should be chosen.
The graded, sun-dried seeds must be

Before storing the sun-dried, graded seeds in gunny bags or polythene bags, they should be treated with carbaryl (5g/Kg of seeds).
the process of making the potting mixture
Prepare the potting mixture with equal parts red soil, sand, and compost in heavy rainfall areas and equal parts red soil, compost, and a little amount of rock phosphate (10g/ 2kg of the potting mixture) in low rainfall areas.

planting seeds
To ensure good germination, the seed nuts should be soaked in water for 12 to 24 hours prior to seeding. The soil in the polythene bag should be moist and loosened at the time of seeding. The seeds should only be sown at a depth of 2.5 cm maximum and cover them with little soil.

Further advice
After seeding, the seed nuts typically germinate within 15 to 20 days. Paddy straw can be used as a mulch over the seedbed until germination occurs, and throughout the summer, partial shade can be supplied.
For cashew plants, a fertilizer dose of 750 g N, 325 g P2O5, and 750 g K2O is advised. Apply a fifth dose once the first year is over, and a second fifth dose during the second year.
In the early growing stages of a cashew plantation, pineapple is the most lucrative intercrop.
Poor soils should have a spacing of 7.5 m × 7.5 m, while rich, deep, and coastal sandy soils should have a wider spacing of 10 m x 10 m.
Within two months of the flowers being fertilized, the fruits will be ready for harvest.
